I have a oscar and a gold channel cat, that will be moved into a new tank in about 3 months. I would like to house them together, i am new to channel cats so i am not shure if this is possible. what size of tank would i need or is this not reccomended? I have had oscars before, just not the channel catfish. I was thinking about a 75 gallon and if my channel cat outgrows that i even have a few ponds lined up that he would love. i would like several suggestions, and possibly is there any other fish that would be good for this tank as well?
